Answer:

Select the Object Selection tool in the Toolbar and drag a loose rectangle or lasso around the item you want to remove. The tool automatically identifies the object inside the area you define and shrinks the selection to the object edges.

The Object Selection tool usually makes a tight selection at the edges of an object. Including some of the area around the object in the selection will help Content Aware Fill create a better fill. Choose Select > Modify > Expand and enter a few pixels—just enough to create a thin border between the edge of the object and the selection. In this case, we entered 8 pixels.

Choose Edit > Content-Aware Fill to open the Content-Aware workspace. The view on the left displays a green overlay that identifies the sampling area Photoshop is considering as it chooses source detail to create the fill. The view on the right is a live preview of the fill, which will change as you refine the result using the tools and controls in this workspace
